ILLUMINATED SIGN.

SPECIFICATION forming part of Letters Patent 'N o. 698,256,da.ted. April22, 1902.

Application filed January 30, 1902. $erial No. 91,898. (No model.)

T0 at whom it may concern;

Be it known that we, GUY D. CHAPMAN and OLOYD R. QUINE, citizens of theUnited States, residing at Akron, in the county of Summit and State ofOhio, have invented a certain new and useful Improvementin IlluminatedSigns, of which the following is a specification.

Our invention has relation to the manufacture of what are known asilluminated electrical signs, and has especial relation to those signsin which the body portion of the letter of which the sign is composed ismade from some non-conducting material, such as porcelain, and in whichthe electrical lamp is partially buried.

The objects of our invention are to produce a new and improved letter inwhich the means for attaching electric lamps shall be made integral withthe main body portion, and it also is one of our objects to so attachthe letter to the supporting-frame that it shall at all times beconvenient to reach all the wires.

. different figures.

Figure 1 is a front elevation of the letter O with the electric lamps inposition. Fig.

2 is a section at the line 00 a: of Fig. 1, and Fig.

vals are holes 3, extending through the main body portion of the letterand nearly to the bottom of sockets 4, which extend from the rear faceof the body portion of the letter. These holes 3 are of such a diameteras will admit the socket end of an electric incandescent lamp. In thebottoms of the holes 3 is a central orifice provided with a shoulder andinto which is placed a screw 5, provided with a shoulder to encounterthe shoulder in the orifice. The upper end of this screw 5 projects intothe opening 3 and is designed to mesh with the female threads in thelampsockets and form one of the electric connections of the lamps.Around and substantially concentric with the opening 3 at its bottom isplaced a bent ring 6, fastened by two screws 7, which pass through theearthenware bottom of the letter and fasten to a semicircular plate 8011 the bottom of the socket. The lower end of the screw 5 is threadedand meshes into a contact-plate 9, also on the bottom of the socket 4.On the plates 8 and 9 are screws 10, to which are fastened the wires forthe lighting of the lamps, the current passing up from plate 8 by screws7 to the'ring 6 and thence to the lamp and returning by the screw, 5 andcontact-plate 9. These sockets t are made integral with the main bodyportion of the letter, and the diameter of the base portion of thesesockets is larger than where the socket joins the letter and aresubstantially f in a dovetailed form. The letters are attached to theboard 1 by making openings in the board large enough to admit thesockets, and the bodyportion 2 of the letter is brought accurately downon the surface of the board,

and the space around the narrow portion of the socket is filled withsome cement, preferably plaster-of-paris, by which means the letter isaccurately attached and firmly held in position when the cement dries.

We are aware that advertising-signs made .by attaching rows ofincandescent lamps to a board arenot new, and this we do not claim.

What we do claim, and desire'to secure by Letters Patent, is-' 1. Thecombination in aletter for signs, of a body portion, and dependingsockets for the reception of incandescent electric lights made integralwith said body portion.

2. The combination ina letter for signs of.
